At the conclusion of this exercise, students will be able to use gestures to communicate about Miller Indices.
Context for Use
This exercise follows a short lecture on Miller Indices and an assignment to determine Miller Indices of forms on wooden blocks, in an undergraduate Mineralogy course. It is intended to give students practice using Miller Indices to communicate about the orientations of surfaces.
Description and Teaching Materials
In this exercise, students use one hand to gesture crystallographic axes and the other hand to represent planes designated by Miller Indices. This uses embodied learning to reinforce how Miller Indices are used to convey spatial information.

I walk around the room and verbally quiz students as they are doing the exercise to assess their understanding.
